Application led August 13, 1925.V Serial No. 50,044.1.l

To all whom t may concern.' Be it known that I, EDMUND S. SPINNEY, citizen of the United States, residing at Abington, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Tag-Patching Machines, of which'the following is a speciiication. l This inventi'onrelates to a machine 0rganized to simultaneously cut two circular reinforcing patches-:trom gummed strips of` paper or 'other suitable material; press the patches against opposite sides of a tag and perforate'the tag and the patches to iorm a The patches are cut by m-ale and female cutting dies acting within guides having slots through which the gummed strips pass in the path of the male dies. rIhe guides and dies become coated with adhesive rubbed from the strips, and require frequent removal from the machine in order that they may he cleaned.

VOne object lot the invention is tovenable the guides and the dies cooperating therewith to be removed from the frame and other parts of the machine, `:to be cleaned,V

and then replaced quickly and conveniently without employing an skilled machinist and with a minimum expenditureof time. i

Another object is to so improve the mechanism for operating the movable dies Vas to cause a more effective pressure oi the patches against the tagA than heretofore. l

I attain the above mentioned and other incidental objects by' the improved construction hereinafter Ydescribed and claimed.

' Off the .accompanying drawings forming a part otthis speciticatiom- ,Figure 1 is an end view of a machine embodying my improvements, the usual means for moistening the gummed strips and feeding them tovand from the machine, being omitted. 'Y

` The frame of the machine is designated as a. whole by 12 and maybe of any suitable OI'III., elongated and provided with upper and lower bearings 13 for the driven shaft-sconstitu-t-ing elements,k of the mechanism for operating the movable dies. The frame is provided between said bearings with a she-lf or table 14C on whicha tagismoved by hand to position to receive the reinforcing patches. 15, 15 designate the aligned tubularguides in which the movable dies (hereinafter described)Y are reciprocated The guidesV are fixed to the frame with their bores in'alignment with each other, their adjacent `ends being sufficiently spaced apart'to permit the insertion of a tag between them.l The vguides are providedwith slots larranged to lguide gummed strips 17 across the bores' of the guides.vv -V In accordance with my invention, I provide the frame with recessed positioning ing thel sides'ofa-n'approximately 'V-shaped recess, and the guideshavecylindrical peripheriesconcentric 'with their bores. I prefer to embody the clamping means in tension rods-2O- ixed tol'the guides and Vremovably inserted in 'orifices'Vl extending V'through the frame, the rods being threaded at their Vouterl ends and provided with Figure 10` shows an ordinarylshipping" The trame is preferably vertically vabutments, 18 for the guides y'15, and asso.-

lOl

' clamping nuts 21.

Then Vthe nuts are turnedinward against a face of the frame 12, the guides 15 are clamped against and positioned by the abut-ments 18, and when the nuts are removed, the guides and their tension rods are removable from the frame.

The machine includes the usual male and female patch-cutting dies 22 and 23 (Figures 7, 8 and 9) adapted to cut patches 29 (Figure 10) from the gummed strips 17, and the usual male and female perforating dies adapted to form holes 7L in the patches and'in a tag against the opposite sides of which the patches have been pressed. The female patch-cutting dies 23 are fixed in the guides 15. rlhe male patch-cutting dies 22 are guided by and reciprocated in the guides 15, said dies having'elongated shanks 22a vhaving a sliding fit in the boies of the guides. The perforating dies include a single male die 24 movable in the bore of the upper punch-cutting die 22, and provided with a shank 24a projecting from the shank 22a, and a single female die 25 formed by the intersection of the bore and the acting j end of the lower male patch-cutting die 22. Y Then the dies 22 are retracted as shown by Figure 7, the gummed strips 17 are movable in the guides by usual feeding mechanism (not shown) organized to hold the strips at rest whenvthe cutting and perforating dies are acting. When the dies 22 are projected, t-wo patches are cut and pressedagainst the sides of the tag as shown by Figure 8, the male perforating die 24 remaining in a retracted position. While the male dies 22 are projected, the male perforating die 24 is projected as shown by Figure 9, and forms the hole 72., the blanks cut .from the patches and tag' passing downward through the Vbore of j the lower male die 22.

The male perforating die 24 is pressed up- I ward by a spring 28 against the upper one of two operating eccentrics 29 fixed to upper and lower driven shafts 30 j ournalledy in the bearings 13.` The shafts may be driven by a motor (not shown) connected with one of the shafts and by a sprocket chain 31 engaged with sprocket wheels 32 fixed to the shafts.V The eccentrics 29 are provided with elongated cam-shapedV projections 32 eX- tending from end to end of the eccentrics and arranged to bear on spaced apart trimdle rolls 33 (Figure 5) mounted loosely on ears 34 formed on heads 35 fixed to the shanks 22a of the male punch-cutting dies.

- The eccentrics 29 are provided with wrist pins 36 eccentric to the shafts 30 and connected by links 37 with studs 38 fixed to ears 34 of the heads 35. The movement of the eccentrics from the position shown b-y Figure 7 to that shown by Figures 8 and 9, causesV the eccentrics to project the male punch-cutting dies.

The function of the links is to retract the male patch-cutting dies when the ecc'entries are ii'ioving from the position shown by Fig- 4) is provided with a central cam-shapedV projection 40v diametrically opposite the projection 32 of that eccentric and arranged to pass between the trundle rolls 33 on the upper head 35. The shank 24n of the male perforating die 24 projects between the trundle rolls into the path ofthe cani-shaped projection 40, the arrangement being such that the 'projection 40 projects the male perforatingdie as shown by Figure 9. shank 24n is preferably provided with an anti-friction ball 41 contacting with the up per eccentric and its cam-shaped projection 40.

The links 37 are slidable on the wrist-pins to the. right from the positions shown by Figure 2, and are confined on the studs 38 by split collars 42, secured to the studs by clamping screws 43.

lt will now be seen that to permit theremoval of the guides 15 Vand the various dies from the machine, it is necessary only toV remove the clamping nuts 21, these being re.- movable by an attendant, who is not necessarily a machinist. Vfhen the nuts are removed, the guides, the dies, and the links 37 may be freely moved to the right from the positions shown by Figure 2;

, It will also be seen by rererence to Figures 7, 8 and 9, thatrthe male patchfcutting diesV are held projected and press the patches against the tag while the eccentrics are movring from the positions shown by Figure 8, to

and beyond the position shown by Figure 9., the cam-shaped projection 40 acting through the shank 24a and the spring 28 to hold the upper male die projected while said projection 40 is moving across the shank 24a, so that a prolonged pressure of the patches against the tag is caused bythe portions of the eccentrics between the points and jl/ (Figure 8).
